When a photograph 20 (or any other item, such as a drawing, a blank sheet of paper, a canvas or other fabric, etc.) is mounted between the front cover 10 and a back cover 30, it becomes another component of a single display unit 100.

FIG. 3 is a back view schematic illustration of a transparent front cover 10 upon which a section plane a-a is marked, according to the present invention.

FIG. 3 shows the d₁ dimension, which is the length of the longest side of the transparent front cover 10. Additionally, FIG. 3 shows the front cover side wall 13 and the front cover face 12 of the transparent front cover 10. When transparent front cover 10 is square shaped, the d₁ dimension is the length of each one of the sides of the transparent front cover 10, in the present view.

FIG. 4 is a back view schematic illustration of a back cover 30 upon which a section plane b-b is marked, according to the present invention.

FIG. 4 shows the d₂ dimension which is the length of the longest side of the back cover 30 and the d₃ dimension which is the height of the back cover angled wall 35. The back cover 30 is comprised of horizontal support beams 31, a back cover face 32, back cover side walls 33, vertical support beams 34 and back cover angled walls 35.

When the dimensions of the back cover 30 are small enough, it is possible to eliminate the horizontal support beams 31, vertical support beams 34 or both.

When transparent front cover 10 is square shaped, the d₂ dimension is the length of each of the sides of the transparent front cover 10, in the present view.

The back cover 30 has a back cover angled walls 35 in order to prevent excessive pressure during the insertion of the back cover 30 into the transparent front cover 10 as well as to ease the separation of the two covers.

The back cover angled walls 35 can be, from a top view, shaped as a straight line, which is practically at an angle of 135 degrees to the back cover side wall 33 or at any other angle suitable to allow space for an attachment clip 60 when attaching single display units 100 to each other.

Attachment clip 60 and single display units 100 are not shown in the present illustration however are shown in subsequent illustrations.

Likewise, the back cover angled walls 35 can be, from a top view, of a curved shape, such as a segment of a circle, ellipse, etc.

FIG. 5 is a cross sectional view a-a of an illustrative embodiment of a back cover 30, according to the present invention. The illustration marks detail A in a circle, which is magnified in the circle on the left side of the illustration.

FIG. 5 shows the d₄ dimension which is the outer width of the side of the back cover 30, and d₅ which is the outer height of the back cover side walls 33. The vertical support beam 34 shown in this cross sectional view is shown as an open channel, but it may also be solid with no voids.

In detail A, it is possible to see the back cover side wall exterior face 36 is set at an angle α relative to the back cover back face 37.

FIG. 6 is a cross sectional view b-b of an illustrative embodiment of a transparent front cover 10, according to the present invention.

The illustration marks detail B in a circle, which is magnified in the circle on the left side of the illustration. FIG. 6 shows the d₆ dimension, which is the inner width of the side of the transparent front cover 10 and d₇, which is the inner height of the front cover side walls 13.

In detail B, it is possible to see the front cover side wall inner face 16 is set at an angle β relative to the front cover back face 17.

Angles α and β are chosen so that α is larger than β so that when the back cover 30 is inserted into the transparent front cover 10, the back cover 30 latches onto the transparent front cover 10 due to the friction generated by the two covers.

One example of the values for these angles, which is in no way limiting to the present invention, is angle α having 90 degrees and angle β having 87 degrees.

The dimensions d₄ and d₆ correspond with each other so that when the back cover 30 is inserted into the transparent front cover 10, there is sufficient friction between the two covers to retain the back cover 30 within the transparent front cover 10.

The value selection of angles α and β and dimensions d₄ and d₆, for the purpose of serial production of the transparent front cover 10 and the back cover 30, can be determined by means of trial and error, after manufacturing and examining several models.

The dimensions d₅ and d₇ are chosen so that d₅ is smaller than d₇, when the difference is practically in the thickness dimension d₈ of front cover face 12, so that when the back cover 30 is inserted into the font cover 10, the front cover 10 overlaps with the back cover 30.

FIG. 7 a is an isometric rear view schematic illustration of an exemplary, illustrative embodiment of a single display unit 100, according to the present invention.

In this figure it is possible to see how the back cover 30 fits within the transparent front cover 10.

FIG. 7 b is a side view schematic illustration of an exemplary, illustrative embodiment of a single display unit 100, according to the present invention.

The friction forces active between the back cover 30 and the transparent front cover 10 are at least strong enough to prevent any separation as a result of gravity force, even when there is a picture placed between them, namely the friction force is no smaller than the weight of the heavier of both units. The present illustration shows the transparent front cover 10 harnessed and immovable, while the back cover 30, which is facing downward, is subject to a gravitational force W, however it does not fall down, due to the cumulative friction forces F, which are active between the back cover 30 and the transparent front cover 10.

The attachment clip 60 is comprised of two main components: an attachment springy clip body 62 and two attachment clip handles 62.

When the user presses the attachment clip handles 62 inwards, towards each other, the attachment clip handles 62 pull open the attachment clip body 61. When the user releases the attachment clip handles 62, the attachment clip body 61 closes.

FIG. 9 a is an isometric schematic illustration of a partial cutout of an attachment clip 60 attaching two single display units 100, according to the present invention.

In order to attach two single display units 100, one needs to place the two single display units 100 so that their front cover side walls 13 touch each other and then, apply the attachment clip 60 to them. Subsequently, the attachment clip handles 62 can be flattened down onto the back covers 30 or removed from the attachment clip 60.

The clip handles 62 can be removed from and reassembled to attachment clip 60. The attachment clip 60 is one possible means of attachment of the single display units 100 to each other, according to the present invention; however, it is in no way limiting the present invention from use of any other means of attachment.

In this figure, the attachment clip handles 62 are flattened down onto the back covers 30.
